However, it is important to use the proper foliar substance and apply it at the proper time and concentration. Recently, it has been observed that there are a limited number of studies on phenylalanine and proline applications in improving grape quality. In current research, three different doses (0, 500 and 1000 ppm) of phenylalanine (Phe) and proline (Pro) were used alone or in combination with bunch tip reduction (Btr) application in order to determine their effects on grape quality attributes. As a consequence of this study, particularly Phe-1000 ppm + Btr was found to be the most favorable application for improving phytochemical properties of 'Red Globe' table grape variety.en10.1007/s10341-024-01110-yinfo:eu-repo/semantics/closedAccessGrapeFoliar applicationsAmino acidsBunch tip reductionPhytochemicalsArticle66415791587N/AWOS:0012301135000012-s2.0-85199541885N/A
